Do you have the SELinux boolean 'nis_enabled' turned on?

# setsebool -P nis_enabled 1

That should be required for NIS logins to work, I believe.

Check out if there are other SElinux AVCs, by trying to log in and
then run:

# ausearch -m avc -ts recent

This will show any AVCs on the system from the past 5 minutes.
Replace 'recent' with 'today' to show all from today.
